irrigation / home automation Arduino ino code

Here are the legacy RainBird solenoids for the front and rear of the house. The left valve controls water to the rear, while the right value the front. Next to the hole is the main shutoff valve which leads to the street main.  

Here is the new wiring connecting the new internet of things (IOT) controller to the solenoids of my previous day's post and the 12 VAC power supply. I reused the RainBird power supply.

And a closeup of the IOT controller in action. This morning was the first day. The control worked OK -- the valves turned on at sunrise and turned off fifteen minutes later. I placed the Arduino UNO INO source code licensed with the GNU GPL at GITHUB at the link https://github.com/str255/esp8266-irrigation-controller
